Only one item can be delivered at a time. It can’t weigh more than 5 pounds. It can’t be too big. It can’t be something breakable, since the drone drops it from 12 feet. The drones can’t fly when it is too hot or too windy or too rainy.
You need to be home to put out the landing target and to make sure that a porch pirate doesn’t make off with your item or that it doesn’t roll into the street (which happened once to Lord and Silverman). But your car can’t be in the driveway. Letting the drone land in the backyard would avoid some of these problems, but not if there are trees.
Amazon has also warned customers that drone delivery is unavailable during periods of high demand for drone delivery.
If you factor in all the logistics and systems necessary to run the drone operations and all associated functions, is it likely to be much of a saving?
I could see something like this as useful for medical prescription delivery, but that comes with its own issues and dangers.
Yeah, almost definitely. Even if those systems have a relatively high power draw, they’re still not being powered by a low efficiency ice engine but are being powered by a grid that’s only getting greener. Also factor in the fact that a car+person is minimum about 1100kg that needs to be transported as opposed to the low weight items plus the weight of the drone (can’t be more than 2-3 kg)
